DETAILED DESCRIPTION

In the following description, reference is made to the accompanying drawings that form a part hereof, and in which is shown by way of illustration specific embodiments which can be practiced. These embodiments are described in sufficient detail to enable those skilled in the art to practice the invention, and it is to be understood that other embodiments can be utilized and that structural, logical and electrical changes can be made without departing from the scope of the invention. The following description of example embodiments is, therefore, not to be taken in a limited sense, and the scope of the invention is defined by the appended claims.

The functions or algorithms described herein can be implemented in software or a combination of software and human implemented procedures in one embodiment. The software can consist of computer executable instructions stored on computer readable media or computer readable storage device such as one or more memory or other type of hardware based storage devices, either local or networked. Further, such functions correspond to modules, which are software, hardware, firmware or any combination thereof. Multiple functions can be performed in one or more modules as desired, and the embodiments described are merely examples. The software can be executed on a digital signal processor, ASIC, microprocessor, or other type of processor operating on a computer system, such as a personal computer, server or other computer system.

In customer facing retail environments, such as grocery stores, discount stores, etc., the design and planogram of the shopping environment is typically designed for shopper experience. It is not designed to facilitate the creation of voice workflow applications that need explicit identification of location of items and products through oral communications.

To provide a mechanism for providing oral location directions to find a location where a product can be on display, identifiers that accentuate the shopping experience can be used. Instead of using unfriendly alpha numeric representations of location, guidance, via a headset, can be provided using more visually pleasing, universally identifiable indicators that fit into the thematic styles of a given retail environment can be used. Ideally, these indicators would be invisible to the customers, or visible and easily identifiable for customer location. At the same time, these should be completely obvious to workers for identification purposes.

Prior oral directions have been provided based on a planogram of a shopping environment. For example, a typical warehouse location for a product can comprise: “Produce, Aisle 15, Slot 120-1.”

This location can also have a check-digit for verbal verification in voice workflow applications, such as a number, for example: “25.” A worker receiving the oral directions would use signs in the warehouse or shopping environment that identified aisle 15 and slot 120-1 to find the product, and then say the check-digit, “25” to inform a system that the product has been successfully located. The check-digits can also be on the product or a label proximate the product in a manner to clearly indicate that they are the check-digits for the corresponding product.

This location and check-digit representation is unacceptable for retail shopping environments. Instead, imagine the following location description: “Produce, Aisle 15, Brown (shelf), Pumpkin (section.)” The term “produce” can correspond to aisle 15, where a produce type decoration can be displayed, or can refer generally to where produce is displayed. The remaining terms, “brown” and “pumpkin” can refer to decorations that are provided in the store, which can be part of a decoration theme in one embodiment, or otherwise selected.

Instead of a numerical check digit, the product can have an associated visual symbol that can look like an in store decoration that the worker might describe as, for example, a: “Bullseye”

In this example, each shelf might be decorated with a consistent color of trim for each shelf. Brown could be the bottom shelf, followed by orange, then yellow, then red. To the customers, this would be intended to look like a pleasing fall seasonal decoration. Note that the term “pleasing” is not meant as a subjective term, but rather the intended effect by a store designer attempting to create an environment that fits a business strategy of the store. In addition, there can be a decoration on the top of the section of shelves. At this location it can be a pumpkin. Others might have a scarecrow, cornstalks, etc. Many different themes, such as holiday, animal, fish, fruit, vegetable, sports, can be used and can change throughout the year or based on the type of merchandise being displayed. This combination of decorations can be used to provide precise oral descriptions of locations to the workers.

Similarly, each location can be marked with some, small, innocuous, or even theme consistent, check-digit decorator. Instead of reading back a check-digit made up of numbers, the user can describe the decorator. In this example, it could be a target bullseye or other symbol. In further embodiments, it can include a couple sets of multiple symbols, each set corresponding to a value of a digit of the check-digit, such as a set of three bullseyes and a set of two bullseyes, corresponding to the check digit “32”. Combination of decorators can be used to provide the same level of precise location and verification as the much less user friendly warehouse technique of numbers and letters displayed throughout the layout of the warehouse environment.

In an embodiment shown in FIG. 1, a distributed headset 100 is a wireless enabled voice recognition device that utilizes a hands-free profile, where increased battery life is obtained by off-loading elements of the traditional headset into an external electronics module 110 (“module”). The module 110 can communicate with a server 116 to receive a batch of activities, referred to as a workflow or work queue. Server 116 can have one or more user or operator computers attached to direct workflow, one of which can also receive wireless signals from the module 125 to interface between the headset 110 and server 116. In an embodiment, the server 116 can provide the distributed headset 100 with a single activity at a time.

The external module 110 is coupled to a light-weight and comfortable headset 115 secured to a worker head via a headband 117. The headband 117 can be a band that is designed to be secured on a worker's head, in an ear, over an ear, or the like. In an embodiment, the headset 115 includes one or more speakers 120 and one or more microphones 125, 126. In an embodiment, microphone 125 is a conventional microphone that converts sound waves into analog signals. Microphone 126 can be one or more microphones that provide for noise cancellation continuously receiving and blocking environmental sounds to enhance voice recognition and optionally provide for noise cancellation.

The external electronics module 110 houses several components typically incorporated in a conventional headset. Thus, the distributed headset 100 reduces the weight of the headset 115 by incorporating heavier components, such as the battery, into the external module 110. In the embodiment shown in FIG. 1, the external module 110 houses one or more of a rechargeable or long life battery, keypad, Bluetooth® antenna, and printed circuit board assembly (PCBA) electronics. The module 110 can include a lapel clip or a lanyard to facilitate attachment of the module 110 to the worker's torso.

In the embodiments shown in FIGS. 1 and 2, the headset 115 is communicatively connected to the electronics module 110 via a communication link 130, such as a small audio cable 130 a shown in FIG. 1, or wireless link 130 b shown in FIG. 2. The distributed headset 100 provides a flexible use case across multiple workflows in multiple markets, such as grocery retail, direct store delivery, healthcare, etc. In some embodiments, the distributed headset 100 has a low profile and is not intimidating to a customer in a retail setting. Thus, in some embodiments, the headset 115 can be minimalistic in appearance in an embodiment.

In an embodiment, the cable 130 a electrically connects the battery in the module 110 to the headset 115 and provides a source of power to the headset 115.

In an embodiment, module 110 can be used with different headsets, such as Honeywell Vocollect™ headsets, depending on environment.

In an embodiment, the headset electronic circuitry package 135 includes a memory 136 that stores the unique identifier of the headset 115. The headset electronic circuitry package 135 electronically couples the memory 136, speakers 120, and microphones 125 to the electronics module 110. In an embodiment, the audio cable 130 includes multiple conductors or communication lines for signals which can include a speaker+, speaker−, ground digital, microphone, secondary microphone, microphone ground, among others. The module 110 optionally utilizes a user configurable attachment 140, such as a plastic loop, and attachment position on the worker. In embodiments comprising a wireless link between the headset 115 and module 110, such as Bluetooth™ type of communication link, the headset 115 includes a small, lightweight battery, where the communication link 130 provides wireless signals suitable for exchanging voice communications.

In the embodiment shown in FIG. 2, an architecture 200 of distributed headset system 100 provides communications to a worker. The architecture 200 includes the headset 115 and external electronics module 110. Module 110 can be coupled to the server 116 or other device, such as a terminal 210 via a wireless link 215, such as a Bluetooth® connection. The terminal 210 can be further coupled to a network 220 via a wireless or wired connection 225, such as WLAN, or other common wireless protocols, and further coupled via a wired or wireless connection 230 to a voice console 235. The voice console 235 assigns an operator to the terminal 210. Voice templates can be stored in terminal 210 to recognize worker voice interactions and convert the interaction into text based data and commands. The data and commands can interact with an application running on the terminal 210.

Those of ordinary skill in the art would appreciate the functions ascribed to individual elements of the architecture 200 can be performed in one or more locations. For example, in an embodiment, the terminal 210 can perform voice recognition, or in another embodiment, the module 110 can perform voice recognition utilizing the voice templates. In an embodiment, first stages of voice recognition can be performed by the module 110, with later stages being performed on the terminal 210. In an embodiment, raw audio is transmitted from the module 110 to terminal 210 where the later stages of recognition can be performed.

In an embodiment shown in FIG. 1, a mobile device 150 is communicatively coupled to the server 116. The mobile device 150 can be a tablet, laptop, smartphone, or any other portable electronic device known to those of ordinary skill in the art. The mobile device 150 includes a visual display 151. Mobile device 150 can communicate with a server 116 to receive a batch of activities, again referred to as a workflow or work queue. Mobile device 150 can display the workflow on the visual display 151 in graphical or textual form, or both graphical and textual form, such as the display shown in the embodiments of FIGS. 7 and 8. Server 116 can have one or more user or operator computers attached to direct workflow, one of which can also receive wireless signals from the mobile device 150. Mobile device 150 is coupled to the server 116 via a wireless link 215, such as a Bluetooth® connection, or coupled to the server 115 via a wireless or wired connection, such as WLAN, or other common wireless protocols.

In an embodiment shown in FIG. 3, a coordinate correlation table 600 correlates coordinate based locations in an environment with symbol based locations consistent with a decoration theme. In table 600, a column of aisles in the environment includes aisles 1-N as indicated at 610. A next column 615 describes each symbol associated with each aisle. Column 620 identifies a shelf, with column 625 identifying a section of the aisle, and column 630 identifies corresponding symbols.

In an embodiment shown in FIG. 4, a coordinate location table 300 correlates products with coordinate based locations of table 600. The locations in table 300 include location coordinates such as would be found in a planogram of the environment and as are commonly used in warehouse environments. For example, four columns are shown in table 300, a product column 310, aisle column 315, shelf column 320, section column 325, and check digit column 330. Further columns can be used to even more precisely define location coordinates in some embodiments.

The check-digit column 330 identifies corresponding check digit to be read back by the worker once the product is found. Tables 600 and 300 can be provided by a database in various embodiments, either as stand-alone tables, or tables derived from a single comprehensive table. In a further embodiment, a single table can be used to directly provide symbol based coordinates for each product to be located.

Planogram models of the environment can be included in the database in some embodiments. Updating of decorating themes can be correlated in table 600 without modification of table 300 in some embodiments to facilitate decorating theme changes without having to modify the locations of each product individually to reflect the changes.

In an embodiment shown in FIG. 5, method 400 describes providing oral instructions and/or voice based instructions via the distributed headset 100, verbal instructions via visual display 151 of mobile device 150, or instructions in symbol or graphic form on the visual display 151 of mobile device 150 to a worker to locate a product in a retail type of environment utilizing symbols. The method 400 includes receiving an indication of a product to be located as part of a worker workflow at 410; obtaining the location coordinates of the product with the workflow, or from a table 600,300 using the product as a key, by a processor, either at a server or headset level at 415; and determining the corresponding symbols to communicate to the worker from the coordinates for the location via table 600 at 420, each coordinate column, such as aisle, shelf, and section, being used to find the corresponding symbol in table 600. In an embodiment, the tables 600,300 can be merged or joined to provide a single table in a database for identifying the location symbols.

The method 400 can further include once the symbols are identified, communicating the identified symbols to the worker to guide the worker to the location of the product at 425. The symbols can be rendered and provided in audio form through the distributed headset 100, such as oral instructions, or can be provided via a display device in verbal form, or even in symbol or graphic form on a tablet type device or head mounted display. When the worker reads the check-digit, such as by describing the symbol or combinations of symbols associated with the product, method 400 receives the oral communication from the worker reading the check-digit, such as by describing the symbol or combinations of symbols associated with the product, and performing voice recognition to convert the communication to text at 430. The check digit of the product to be located is obtained at 435 and compared to the converted text at 440 to confirm that the product has been found when the check digits match.

FIG. 6 is a block schematic diagram of a computer system 500 to implement methods according to example embodiments, such as the distributed headset 100 and the mobile device 150. All components need not be used in various embodiments. One example computing device in the form of a computer 500, can include a processing unit 502, memory 503, removable storage 510, and non-removable storage 512. Although the example computing device is illustrated and described as computer 500, the computing device can be in different forms in different embodiments. For example, the computing device can instead be a smartphone, a tablet, smartwatch, headset, or other computing device including the same or similar elements as illustrated and described with regard to FIG. 5. Devices such as smartphones, tablets, headsets, and smartwatches are generally collectively referred to as mobile devices 150. Further, although the various data storage elements are illustrated as part of the computer 500, the storage can also or alternatively include cloud-based storage accessible via a network, such as the Internet.

Memory 503 can include volatile memory 514 and non-volatile memory 508. Computer 500 can include—or have access to a computing environment that includes—a variety of computer-readable media, such as volatile memory 514 and non-volatile memory 508, removable storage 510 and non-removable storage 512. Computer storage includes random access memory (RAM), read only memory (ROM), erasable programmable read-only memory (EPROM) & electrically erasable programmable read-only memory (EEPROM), flash memory or other memory technologies, compact disc read-only memory (CD ROM), Digital Versatile Disks (DVD) or other optical disk storage, magnetic cassettes, magnetic tape, magnetic disk storage or other magnetic storage devices, or any other medium capable of storing computer-readable instructions.

Computer 500 can include or have access to a computing environment that includes input 506, output 504, and a communication connection 516. Output 504 can include a display device, such as a touchscreen, that also can serve as an input device. The input 506 can include one or more of a touchscreen, touchpad, mouse, keyboard, camera, one or more device-specific buttons, one or more sensors integrated within or coupled via wired or wireless data connections to the computer 500, and other input devices. The computer can operate in a networked environment using a communication connection to connect to one or more remote computers, such as database servers. The remote computer can include a personal computer (PC), server, router, network PC, a peer device or other common network node, or the like. The communication connection can include a Local Area Network (LAN), a Wide Area Network (WAN), cellular, WiFi, Bluetooth, or other networks.

Computer-readable instructions stored on a computer-readable medium are executable by the processing unit 502 of the computer 500. A hard drive, CD-ROM, and RAM are some examples of articles including a non-transitory computer-readable medium such as a storage device. The terms computer-readable medium and storage device do not include carrier waves. For example, a computer program 518 capable of providing a generic technique to perform access control check for data access and/or for doing an operation on one of the servers in a component object model (COM) based system can be included on a CD-ROM and loaded from the CD-ROM to a hard drive. The computer-readable instructions allow computer 500 to provide generic access controls in a COM based computer network system having multiple users and servers.

In an embodiment shown in FIG. 7, an image of a product to be located can be shown on a screen of a hand held device.

The image in FIG. 7 is a digitized photograph of a jar of sliced mushrooms of a particular brand as shown in the upper left of the visual display 151. The upper left of FIG. 7 also illustrates a graphic which can be created to provide a visual representation of a position on a shelf 153 of a product 152 to be located. The shelves 153 can be represented by a grid showing lines corresponding to each shelf 153 relative to other shelves 153, with the area where the product 152 to be located shown as a shaded portion 154 of a shelf or shelves 153. The shaded portion 154 can be any color, such as red or yellow, or some other color designed to be quickly observable by a worker. The shading portion on the shelf 153 provides an indication of where on the shelves 153 the product 152 is located.

In an embodiment, the grid 153 can be superimposed on an augmented reality view of the actual shelf. The image of the product 152 can be used to highlight the actual products on the shelf 153 via comparison to a stored image of the product 152.

Text that includes a text based description of UPC number 155, description of the product including size and price 156, and aisle and shelf number 157 can also be provided to aid the user in accurately identifying the location of the product 152. A voice description of the location can also be provided via the headset 100 or through a speaker (not shown) integrated into the mobile device 150.

A further example is shown with lima beans in FIG. 8.

In an embodiment shown in FIG. 9, method 700 describes providing instructions in graphic form on the visual display 151 of mobile device 150 to a worker to locate a product in a retail type of environment. Method 700 can be used in concert with method 400, thus providing both audio communication between the worker and the server 116, and a visual display of the product 152 and product location. The method 700 includes receiving an indication of a product 152 to be located at block 701; identifying a location of the product 152 at block 702; communication the location of the product 152 to the visual display 151 at block 703; displaying a digitized photograph of the product 152 to be located on the visual display 151 at block 710; displaying on the visual display 151 a virtual representation or graphical image of a set of shelves 153 on which the product 152 is located at block 715; shading a portion 154 of the shelf or shelves 153 where the product 152 is positioned at block 720; displaying on the visual display 151 a text-based visual description of an aisle and shelf location of the product 152 that corresponds to the virtual representation of shelves 153 and shading portion 154 at block 725; and displaying a text-based visual description of a Universal Product Code (UPC) number 155 for the product 152 at block 730.

Although a few embodiments have been described in detail above, other modifications are possible.
